Each
of
the
grain
weights,
in
addition
to
the
circles
denoting
their
several
weights,
bears
also
the
stamp
of
a
crown.
Care
must
be
taken
not
to
mistake
this
for
one
of
the
numerals.
Besides
these
weights
there
are
others
marked
[*scruple]ss,
which
means
half
a
scruple;
[*drachm]ss,
meaning
half
a
drachm;
and
[*ounce]ss,
meaning
half
an
ounce.
When
there
are
ounces,
drachms,
or
scruples,
the
number
of
them
is
shown
by
Roman
figures,
thus:--i.
ii.
iii.
iv.
v.,
&c.,
and
prescriptions
are
written
in
this
style.

Measures.--Liquid
Liquid
medicines
are
always
measured
by
the
following
table:
60
minims.........
\
/
1
fluid
drachm.
8
fluid
drachms
|
are
|
1
fluid
ounce.
20
fluid
ounces...
|
contained
|
1
pint.
8
pints..........
/
in
\
1
gallon.
And
the
signs
which
distinguish
each
are
as
follows:--c.
means
a
gallon;
o
a
pint;
fl
[*ounce],
a
fluid
ounce;
fl
[*drachm],
a
fluid
drachm;
and
m,
a
minim,
or
drop.
Formerly
drops
used
to
be
ordered,
but
as
the
size
of
a
drop
must
necessarily
vary,
minims
are
always
directed
to
be
employed
now
for
any
particular
medicine,
although
for
such
medicines
as
oil
of
cloves,
essence
of
ginger,
&c.,
drops
are
frequently
ordered.

Specific
Measuring
Vessels.
In
order
that
Medicines
may
be
measured
Accurately,
there
are
graduated
glass
vessels
for
measuring
ounces,
drachms,
and
minims.

Approximate
Measures.
When
proper
measures
are
not
at
hand,
it
is
necessary
to
adopt
some
other
method
of
determining
the
quantities
required,
and
therefore
the
following
table
has
been
drawn
up
for
that
purpose:
